Changes to Spells

Prestidigitation
Allows for firefinger effect to ignite imminently flammable things with a touch. Requires a full round of continuous contact which is rarely practical in combat situations.

Spark
Works on creatures, but only if they are particularly flammable or would reasonably be expected to ignite from a hot spark, e.g. recently drenched in oil. This use of it requires a successful ranged touch attack but does not allow a save.

Orb of Force (and all force spells)
Force-effect spells are all evocation rather than conjuration and allow for Spell Resistance.
